    I get that straight is a straight line, and “cosexual” is the cosine function, but can someone explain the joke for the other two?

      For y = x^2, both x and -x equal to the save value of y.

      For example: 2^2 = -2^2 = 4.

      For the y = sqrt(x), for every positive value of x, there is positive and negative value of y.

      For example: sqrt(4) = -2 = 2.

        I guess I have no idea how the math symbols are supposed to relate to sexual orientation. Can you help with that part?

        Also, IIRC square root of 4 has only one answer: 2, but negative 2 squared is equal to 4. The functions are asymmetric that way? Is that incorrect? This is all from vague memories of high school and college math.

        Does the square root function always give a positive and negative answer? And we in society just kind of forgot about the negative one?

          The rule (meme) came to me in a dream. Dreams are weird, and i have no idea what it is supposed to mean. I just though its funny, and decided to post it.
